The OPC (OLE for Process Control) is a communication standard in the field of control and monitoring of industrial processes, based on Microsoft technology, which provides a common interface for communication that allows individual software components to interact and share data. The OPC communication is done through a client-server architecture. The OPC server is the data source (such as a hardware device at plant level) and any OPC-based application can access that server to read / write any variable offered by the server. It is an open and flexible to the classic problem of proprietary drivers solution. Virtually all major manufacturers of control systems, instrumentation and process have included OPC in their products.
In short this industry standard allows intercommunication between devices and controllers Indistriales protocols almost all brands, performed monitoring and control from HMI, SCADA, PLC and RTU PAC'S
The OPC servers contain the drivers and / or communication protocols of the vast majority of industrial controllers
The OPC clients can be created in a variety of programming languages for reading and / or writing data to the server and there to the industrial controllers. Examples of Architecture OPC (PLC Sensors Actuators - OPC Server and Client OPC)
Has made the integration of Arduino + ESP8266 + Software Opto22, implementing its environment scada right through IP and Modbus TCP Modbus RTU, the idea is to implement this hardware in the industry for both monitoring and control.
1- Arduino MEGA 2560 Master Modbus Potenciometer Display Oled
The Arduino configured as Modbus RTU master sends the value of the potentiometer to the slave in this case a slave simulator.
4- Installation PAC Project Basic and Simulator PAC Sim
process software download and installation of software for Opto 22 controllers in this case download the PAC Project Basic, which includes software programming, design HMI and SCADA Runtime
5- Download Strategy Modbus TCP IP Master in PAC Project Basic Opto22
Opto22 example of strategy setting according to requirement as master or slave Modbus TCP, in this case for integration is configured as Modbus TCP master is discharged are configured holding registers for reading and writing respecting addressing.
Opto 22 is a manufacturing company specializing in hardware and software for industrial automation, remote monitoring, and data acquisition. The company is headquartered in Southern California and is well known in the industry automation and control of its history of innovation in the development of Ethernet relay output status and input / based systems and Controllers.

Introduction
This tutorial will tell you how to download and install the software PAC Project basic for creating HMI scada design and configuration generally based strategies controllers Opto22, then we will make integrations with Arduino and ESP8266 Software Opto22 .. Get ready !!.
PAC Project Basic
This software package is mainly divided into 3:
PAC Control Basic
Entrono building control strategy using 2 programming languages, traditional flowchart and similar or derived language c optoscript, also allows the creation and configuration of PID control loops, the main routines are chart or charts and allows creation Subroutines.
PAC Display Configurator
Creation Environment SCADA or HMI interaction is configured with drivers using a simbol Factory or libraries industrial simbologia (pushbuttons, actuators, pipes, pumps etc), it allows the creation of graphics and trend setting animations shift change colors etc. .
PAC Display Runtime
This application publishes and runs in real time on our HMI or Scada.
Others...
PAC Manager
Software maintenance visualuzacion of variables and more specific settings for Opto 22 controllers.
PAC Sim - simulator Opto22
Opto 22 has a equvalente simulator to have a driver Opto22 one that runs on your PC and have a time of testing and operation since it is a simulator, but in their version PAC Project Professional has SoftPac which if a controller in Software.
